EJ ECTOR FOR FIREARMS.

new and Improved Ej ector for Firearms, ofV

which the following is a specification.

My invention relates to the class of devices employed to remove a cartridge shell from the gripof the extractor and throw it out of the chamber in the receiver of a fire arm after said shell has been withdrawn by the breech-bolt and extractor from the breech chamber in the barrel, and an obj ect of my invention, among Others, is to provide an its operation and so constructed that it shall be extremely strong and durable.

One form of ejector embodying my invention, and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings in which- VFigure 1 is a view in side elevation of the receiver of a firearm with parts broken away to show construction and illustrating a breech-bolt provided with my improved ejector.

Fig. 2 isa top plan view of the same with parts broken away to show my nnproved ejector in place in the breech-bolt. In the accompanying drawings the numeral 5 indicates the receiver of a firearm that may be of any suitable construction and that contains a chamber 6 closed by a side plate 7 and within which chamber a breechi bolt 8 is longitudinally movable. This bolt has openings 9 at its rear end and on oppo- K. site sides thereof within which openings the bolt. All of the parts thus far described may, so far as the invention forming the subject matter of this application is concerned, be of any construction, the construction herein specifically shown forming the filed by me concurrently herewith. The

Specification of Letters Patent.

' illustration and description containedhere`- in, however, are sufficient for a clear under standing of the invention forming the subject matter cfthis case, and many parts not having directly to do with the ejector mechanism are omitted from the illustration.

The breech-bolt 8 has a groove 14 extending longitudinally in one side and within this groove an ejector actuator 15 projects. Preferably this actuator is a screw tting a screw threaded opening in the side walls of.' the receiver and with its end 16 projectinginto the groove 14 and having a cam shaped edge 17 to receive the ejector. f

An ejector groove 18 -is located in the. side of the breech-bolt at its forward end,.

this ejector groove openingat the bottom;k

of the groove 14. This ejector groove comretreat during the operation of the ej ector.

Said ejector 21 is preferably formed of a iat piece of metal comprising a body por. tion 22 and a tail 23. A slot 24 extends through the body of the ejector to receive a retaining pin 25 secured in the breech-bolt and projecting across the groove 18 and through said slot. A plunger 26 has a shank extending into a hole 27 formed in the body of the ejector and opening into one end of the slot 24. A spring 28 located on the shank of the plunger presses with one end against the head of the plun er and with its opposite end against the en of the slot 24 to force the plungerl normally into engagement with the pin 25, this causing the ejector to be held normally in its rearward position as shown in the drawings.

In operation as the breech-bolt is moved backward by the action of the forks 10 of the actuating lever, the end of the tail 23. strikes the cam 17 on the ejector actuator', this causing the ejector to be forced forward against the end of the cartridge shell that is located in a recess 29 in the end of the breech-bolt and that is retained in said recess by the extractor (not shown herein) in the ordinary manner. A shoulder 30 in the end of the ejector is thus forced against the end of the cartridge shell and the latter is by this action of the ejector snapped from the grasp of the extractor and thrown out of the breech-bolt chamber in the receiver through an opening 31 in the side plate 7 of the rev Y n Y v the ejector in said recess torpermit swinging i Y ceiver.

I claim- Y 1. In a firearm embodying a receiver, a breech bolt movably mounted in the receiver, said structure embodying a groove,

van ejector carried by the Ybreech bolt ,andv movable longitudinally thereof, said groove having a cam 'shaped to force Vsaidejector forward'when the latter is pressed laterally against the cam, Vand means on the receiver to engage the ejector andfpress it laterally against the cam, whereby the ejector is Y i Y A l and'having-anejector'recess*withfa cam surf Y face and arest therein, an` ejector-located Y,in 45 forced forward in an ejectiiig movement;

2. VIn a firearm including a receiver, breech bolt Vniovably `mounted therein, Van ejector actuator located on the receiver, said Y l I t swinging movement thereof, meansfor forcbolt having an ejector'recess, an ejector Vlocated in said recess and movable .longitudi nally therein, a tail on the ejector positioned to strike said actuator to force it V forwardly in an Yejecting movement, said tail beingV adapted to pass into said recess Yand under said actuator, and means for forcing the ejector vbackwardly on'the'breech bolt. n 3. In a firearm including af receiver, a

Ibreech-bolt movably 'mounted therein, an

ejector actuator proj ecting from the receiver,

Copies of this-patent may 'be ohtainedpfr Leona/sV Vsaid 'bolt having an ejector recess, an ejector 30V located in said recess, means for retaining and longitudinal nio-vement thereof, said reis in a forward position t to force thefej'ector to its' Vforward position, said tail' .being adapted to pass into said recess and under said actuator, and means for forcing' the 40 ej ector backwardly in the .breech-bolt.

'4. In a'irearin including a receiver, a breech-bolt movably mountedin thereceiver said recess, meansffor ,retaining lthe l'ejector in Asaid recess .toV permitY longitudinal and:
